Yes you need. I was at Puspakom and there's a father and daughter doing internal name transfer among both of them also they are at Puspakom. It's a must for name transfer.

It's a way they implement to protect the second hand buyer and the bank. Previously I think it's a not necessary thing to do but now when I think of it, I think it's a good implementation. Imagine if we were to buy a 2nd hand car and get cheated on the car condition . It's a pretty fast process. Don't worry.

Perhaps consult Puspakom first to see if need to remove. Maybe they can let it pass? Or keep it under your dad's name temporary.
